British and Greek archaeologists mapped the submerged Bronze Age town of Pavlopetri off the coast of Laconia, Greece, dating to 2800-1000 BC. The intact street plan in the Aegean Sea provides rare evidence of early urban planning.

The rediscovery of the underwater city of Pavlopetri in 1967 evokes Atlantis-like themes in poetry that addresses lost civilizations and the impacts of climate change. Poets such as Derek Walcott have used these motifs to reflect on the fragility of human existence and the enduring legacy of submerged histories.
